DETAILED DESCRIPTION

In the following description, the term ‘information item’ denotes an item that can be selectively contained in a list according to whether the information item has the information intended by the user. Each information item can occupy a display region having a predetermined size.

In the following description, the term ‘shown-information item’ denotes the information item that appears in the list, and the term ‘hidden-information item’ denotes the information item that disappears in the list. Here, if a hidden-information item disappears, this means that the corresponding information item is shrunken or removed from an information display region which the information item occupies in active state.

In the following description, the term ‘shown-information region’ denotes a region for displaying an information item in the display screen of the mobile terminal, and the term ‘hidden-information region’ denotes a region for giving a clue of the hidden information item.

Exemplary embodiments of the present invention are described with reference to the accompanying drawings in detail. The same reference numbers are used throughout the drawings to refer to the same or like parts. For the purposes of clarity and simplicity, detailed description of well-known functions and structures incorporated herein may be omitted to avoid obscuring the subject matter of the present invention.

FIG. 1 is a block diagram illustrating a configuration of the mobile terminal according to an embodiment of the present invention.

As shown, the mobile terminal 100 includes a Radio Frequency (RF) unit 110, an audio processing unit 120, a touchscreen 130, a key input unit 140, a storage unit 150, and a control unit 160.

The RF unit 110 is responsible for the radio communication function of the mobile terminal 100 for transmitting/receiving data. The RF unit 100 includes an RF transmitter for up-converting and amplifying the transmission signal and an RF receiver for low noise amplifying and down-converting the received signal. The RF unit 110 transfers the data received over a radio channel to the control unit 160 and transmits the data output by the control unit 160 over the radio channel.

The audio processing unit 120 includes a codec pack having a data codec for processing packet data and an audio codec for processing audio signal including voice. The audio processing unit 120 converts a digital audio signal to an analog audio signal by means of the audio codec to play out the audio signal through a speaker (SPK) and converts an audio signal input through a microphone (MIC) to a digital audio signal by means of the audio codec.

The touchscreen 130 includes a touch sensing unit 131 and a display unit 132. The touch sensing unit 131 detects a touch input made by the user on the screen. The touch sensing unit 131 can be implemented with one of capacitive overlay type, pressure type, resistive overly type, infrared beam type sensors, or a pressure sensor. The touch sensing unit 131 can also be implemented with other type of sensing devices that can detect a contact of or pressure by an object. The touch sensing unit 131 generates a detection signal including coordinates corresponding to a touch input made by the user and transfers the detection signal to the control unit 160. In case that the user makes a movement gesture without releasing the touch made on the screen, the touch sensing unit 131 generates the detection signal including the coordinates on the movement path and transfers the generated detection signal to the control unit 160. Here, the movement gesture can be categorized into one of a flick in which the movement speed is greater than a threshold speed and a drag in which the movement speed is equal to or less than the threshold speed.

The touch sensing unit 131 can detect a user input made for information display setting. In this case, the user input can be one of a pinch input in which two touch points are drawn nearer to each other in drag speed, a double tap input, a soft key input, etc.

The display unit 132 can be implemented with one of a Liquid Crystal Display (LCD), an Organic Light Emitting Diodes (OLED), and Active Matrix OLED (AMOLED), and output menus, user input data, function setting indication, and other information in the form of visual image. The display unit 132 also displays a booting screen, a standby screen, a menu screen, a call progressing screen, and other application execution screens.

The display unit 132 can present a shown-information region for displaying the shown-information item and a hidden-information region for displaying the hidden-information region. Alternatively, the hidden-information region can be a blank region which is not occupied by any information item. The hidden-information region also can be presented as if the information item is folded. A detailed description of processing the hidden-information item is described later.

Although the description is directed to a touchscreen-enabled mobile terminal 100, it should be noted that the teachings of the present invention can be applied to a mobile terminal implemented without a touchscreen. In such a case, the touchscreen 130 can be modified so as to work only with the display function of the display unit 132.

The key input unit 140 generates an input signal to the control unit 160 in accordance with the key manipulation of the user. The key input unit 140 can be implemented with a keypad having alphanumeric keys and navigation keys along with certain function keys formed at a side of the mobile terminal 100. In case of the touchscreen 130, the key input unit 140 can be omitted. The key input unit 140 can further include at least one soft key for display configuration.

The storage unit 150 stores programs and data necessary for the operations of the mobile terminal 100 and can be divided into a program region and a data region. The program region can store the programs for controlling the operations of the mobile terminal, the Operating System (OS) for booting up the mobile terminal 100, the application programs for playing multimedia contents, and other application programs for supporting the supplementary functions such as camera function, audio playback function, and still and motion picture playback function. The data region stores the data generated according to the use of the mobile terminal 100 such as picture, video, phonebook, and audio data.

The control unit 160 controls the overall operations of the internal function blocks of the mobile terminal 100. Particularly, the control unit 160 controls such that each of the information items constituting a list is shown or hidden according to whether the information item contains the user-intended information. The control unit 160 can include an information display determination module 161. In an alternate embodiment, the control unit 160 can implemented to perform the function of the information display determination module 161.

When a user input is detected, the information display determination module 161 analyzes the information items of the list. The information display determination module 161 determines the shown-information items and the hidden-information items according to a predefined display rule. Here, the display rule is used to determine whether to show or hide each information item depending on whether the information item has the user-intended information, whether the information item is mostly used information item, whether the information item has a priority selection or other urgency/emergency level.

FIG. 2 is a flowchart illustrating an information display method of a mobile terminal according to an embodiment of the present invention.

When entering the menu, the control unit 160 of the mobile terminal 100 controls the display unit 132 to display a list related to the menu (S210). Here, the list includes at least one information item.

Next, the control unit 160 detects a user input made for configuring information display condition (S220). According to an embodiment of the present invention, the user input for information display configuration can be made by a pinch input in which two touch points are drawn nearer to each other and sensed by the touch sensing unit 131. However, this information display configuration request input is not limited to the pinch input but can be made with a double touch at a specific area or button or a soft key designated for the information display configuration.

Next, the control unit 160 analyzes each information item of the list (S230). According to the analysis result, the control unit 160 determines whether to show or hide the corresponding information item (S240). A description relating to the determination on whether to show or hide the information is provided in more detail with reference to FIG. 3.

FIG. 3 is a flowchart illustrating the procedure for determining whether to show or hide an information item in the information display method of FIG. 2.

As shown, the control unit 160 checks the information contained in each of the information items from the list (S310). The type of the information can vary according to the list. For example, if the list is a contact list, the information item can contain the information such as an alphabetical index and a subscriber's contact. Alternatively, the list can contain the information such as a schedule title and content.

After checking the information contained in the information item, the control unit 160 determines whether information item contains the user-intended information (S320), and the procedure branches out to step S330 or S360. If the information item does not contain the user-intended or desired information, the control unit 160 configures the information item as a hidden-information item so as to prevent the display from the list (S360).

Otherwise, if the information item contains the user-intended information, the control unit 160 determines whether to show all of the information items containing the user-intended information in the list (S330). Alternatively, whether to show all of the information items containing the user-intended or desired information can be preconfigured by the user. If it is determined to show all of the information items containing the user-intended information at step S330, the control unit 160 configures the corresponding information item as the shown-information item so as to be shown in the list (S350).

If it is determined not to show all of the information items contained the user-intended information at step S330, the control unit 160 determines whether the corresponding information item contains the relevant representative information (S340). Here, the control unit 160 controls such that the list composed of the information items having specific information is displayed on the display unit 132.

If the corresponding information item contains the representative information, the control unit 160 configures the information item as the shown-information item so as to be shown in the list (S350). The representative information can be different according to the type of the list. For example, if the list is a contact list, the representative information can be an alphabet index for sorting out the registered subscribers into certain groups. In another exemplary case of a daily schedule, the representative information can be the schedule title excerpted from the schedule content.

In contrast, if the information item does not contain the representative information, the control unit 160 configures the information item as a hidden-information item so as to be hidden in the list (S360).

Although the description is directed to the case where the information item is configured to be shown or hidden in the list depending on the whether the information item contains the representative information, it should be noted that the present invention is not limited thereto. For example, the information items can be sorted by priority or urgency/emergency level such that each information item can be configured accordingly.

After configuring the shown-and-hidden information items, the procedure returns to FIG. 2. Finally, the control unit 160 controls the display unit 132 to display the list configured to have the information items (S250). In this case, the control unit 160 can display the shown-information items in at least one information display region.

Meanwhile, the control unit 160 can control such that the hidden-information items are clued in the hidden-item regions indicating existence of hidden-information items or not shown in the list which is described later.

A description is made of the information display methods according to the embodiments (first to fourth embodiments) of the present invention hereinafter.

First Embodiment

FIGS. 4A to 4C are diagrams illustrating exemplary steps of the information display method of a mobile terminal according to the first embodiment of the present invention.

When entering the contact list menu mode, the mobile terminal 100 displays the list of contact items representing contacts (e.g., individual, organizations, or corporations) sorted by an order as shown in FIG. 4A. The contact list includes at least one alphabetic group 410 and 420 composed of at least one contact item 430 and 440. In this case, the contact items are classified into alphabetic information groups, and the alphabet indexing each alphabetic information group can be the representative information of the alphabetic information group.

As shown in FIG. 4A, it is impossible to display all of the contact items in the size-constrained display screen of the display unit 132. Accordingly, the user has to scroll up and down the list to search for a specific contact item. In order to mitigate the inconvenience of the scroll manipulation, the information display method of according to the present invention can display only the representative information in alphabetical order so as to provide the user with an overall view of each class/category for a quicker retrieval. To this end, if the user makes a pinch gesture as denoted by the reference number 445, the control unit 160 interprets the pinch gesture as an information display configuration command. Although the information display configuration command is input by the pinch gesture, other variation of hand inputs by a user can be used.

If the user input is detected, the control unit 160 analyzes the information item groups 410 and 420 and the information items 430 and 440 according to a predefined rule and classifies the information items into shown-information items and hidden information items. As shown in the embodiment of FIG. 4A, each of the alphabetic groups 410 and 420 includes the information of an alphabetic index, and each of the contact items 430 and 440 includes the information of registered contact.

When the information display configuration command is input, the predefined rule can be set so that only the representative information, i.e, alphabetical index, is displayed.

As described above, the alphabetic index can be the representative information in that it can be used for classifying the registered contacts into groups. Accordingly, the control unit 160 configures the information item groups 410 and 420 having the alphabet indices as shown-information items and the information contact items 430 and 440 as hidden-information items.

Thus, the control unit 160 controls such that the information groups 410 and 420 configured as shown-information items are displayed on the display unit 132.

FIG. 4B is a diagram illustrating an intermediate step of the information display method according to the first embodiment of the present invention.

In order to provide an aesthetic interface to the user, the control unit 160 can display the hidden-information items in half-folded shape as shown in FIG. 4B. Although they have been depicted in half-folded shape in FIG. 4B, the hidden-information items can expressed in other shape according to another embodiment of the present invention. For example, the contact items 430 and 440 can be arranged in the form of rounded curves or partially overlapped bars.

FIG. 4C is a diagram illustrating a screen after the intermediate step above where the contact list showing only the shown-information items are displayed according to the first embodiment of the present invention

As shown in FIG. 4C, the contact list screen can be collapsed to include at least one shown-information region 450 and at least one hidden-information region 460. The shown-information regions 450 are indexed by the alphabets (i.e., A, B, C . . . ) and the hidden-information regions 460 are processed as blank spaces without displaying any information. In this manner, the contact list is displayed only with the information items having the representative information so as to provide the user with a greater overview of the large amount of information on the size-constrained display screen. As a result, the user can navigate to the desired subclass of information quickly without the need of scrolling down the screen.

Although they are processed as blank spaces in FIG. 4C, the hidden-information region can be expressed in different way. For example, the hidden-information region 460 can be displayed in the form of icon or text for indicating the existence of hidden-information item.

Second Embodiment

FIGS. 5A to 5C are diagrams illustrating exemplary steps of the information display method of a mobile terminal according to the second embodiment of the present invention.

The second embodiment is similar to the first embodiment except that the contact list is composed of the user favorite contact items (or the contact items frequently selected to place a call).

When entering the contact list menu, the mobile terminal 100 displays the list of contact items representing contacts sorted by an order as shown in FIG. 5A. In FIG. 5A, the contact list includes at least one alphabetic group item 510 and 520 composed of at least one contact item 515 and 520. Similar to the first embodiment, each of the alphabetic group items 510 and 520 has the representative information shared by the contact items thereof.

As shown in FIG. 5A, the contact items can be assigned priority according to the user configuration. The priority can be determined according to the frequency or total time of the call to the corresponding contact or weight assigned to the contact. The contacts to which the priority is given are marked with symbols 530, 540, and 550. Alternatively, the user can pre-designates the preferred contact items for selection.

If a pinch gesture is made on the screen as denoted by reference number 555, the control unit 160 interprets the pinch gesture as the information display configuration command. The information display configuration command is input, the control unit analyzes the alphabetic group items 510 and 520 and the contact items 515 and 525 according to a predetermined rule and classifies the contact items into the shown-information item and hidden-information item. For this purpose, the control unit 160 determines whether the contact items 515 and 535 contain the information. As described with reference to FIG. 4A, all of the information items constituting the contact list include the information.

Since the alphabetic index is assumed as the representative information, the control unit 160 configures the alphabetic group item 510 and 520 having the alphabetic index as the shown-information items as in the first embodiment. However, in the second embodiment, the control unit 160 determines whether there is any information item to which the priority is given in the contact list. To this end, the control unit 160 identifies the information items to which the user has assigned the priority with the symbols 530, 540, and 550, and configures the information items having the priority as the shown-information items. Next, the control unit 160 configures the rest information items to which no priority is assigned as the hidden-information items.

FIG. 5B is a diagram illustrating an intermediate step of the information display method according to the second embodiment of the present invention.

In order to provide an aesthetic interface to the user, the control unit 160 can display the hidden-information items in half-folded shape during collapsing. Although they have been depicted in half-folded shape in FIG. 5B, the hidden-information items can expressed in other shape. For example, the contact items can be arranged in the form of rounded curves or partially overlapped bars.

FIG. 5C is a diagram illustrating a final screen outputting the contact list showing only the shown-information items according to the second embodiment of the present invention.

As shown in FIG. 5C, the contact list screen can include at least one shown-information regions 570 and at least one hidden-information region 570. The shown-information regions 570 are used for presenting the alphabetic group items 510 and 520 and the contact items 530, 540, 550, 560 to which the priority is given, and the hidden information regions 575 are displayed as blank spaces or in the form of icon or text for indicating existence of hidden-information item.

Third Embodiment

FIGS. 6A and 6B are diagram illustrating exemplary steps of the information display method of a mobile terminal according to the third embodiment of the present invention.

When entering a daily schedule menu, the mobile terminal 100 displays a schedule list organized by time interval as shown in FIG. 6A. In FIG. 6A, the schedule list includes the items 601, 602, and 603. Reference number 601 can be classified into non-scheduled item, and reference number 602 can be classified into schedule item. In this case, each of the schedules 615 and 640 includes a title 620 (650) and a schedule content 630 (660). Since it is important to identify the schedule for a specific time interval in the schedule list, the schedule title can be assumed as the representative information.

The control unit 160 detects a user input for the information display configuration. If the user input is detected, the control unit 160 analyzes the items of the schedule list according to a predetermined rule to classify into the shown-information items and hidden-information items. For this purpose, the control unit 160 determines each of the items 601, 602, 603, . . . contains information. Then, the control unit 160 configures the non-scheduled items, i.e. the items having no information, as hidden-information items.

Next, the control unit 160 determines whether to display all of the scheduled items on the display unit 132. In this case, the schedule list can be preconfigured such that, when the information display configuration command is input, the items having the representative information are displayed. Here, the schedule titles 620 and 650 can be the representative information in the schedule list. That is, the control unit 160 can configure the items having a specific title as the shown-information items as these items are more relevant in this mode. Accordingly, the control unit 160 identifies the items having the representative information to be displayed on the display unit 132, as shown in FIG. 6(B).

FIG. 6B is a diagram illustrating a screen outputting a contact list having the shown-information items according to the third embodiment of the present invention.

As shown in FIG. 6B, the display unit 132 displays the schedule list having at least one shown-information region 690 and at least one hidden-information region 695 as the result of the information display method according to the third embodiment of the present invention. The shown-information region 690 is used to present the titles 620, 640, 670, and 680 of the shown-information items, and the hidden information region 695 is processed as blank space or in the form of icon or text for indicating existence of hidden-information item, so that the user can see more of the relevant information in a single screen to minimize the scrolling action. Here, the hidden-information region 695 can be presented in the shape of multiply folded paper, rounded curves, or partially overlapped bars.

FIGS. 7A and 7B are diagrams illustrating exemplary steps of the information display method of a mobile terminal according to the fourth embodiment of the present invention.

When entering an email menu, the mobile terminal 100 displays a list of emails as shown in FIG. 7A which includes the unread email items 710 (indicated by shade lines) and read email items 720. During this mode, the predefine rule can set to display a list of the unread email items. To this end, the unread email items 710 are assigned a priority higher than that assigned to the read email items 720.

The control unit 160 detects a user input requesting for information display configuration analyzes the information items to classify into shown-information items and hidden-information items. The control unit 160 first determines whether each of the information items contains user-intended information. In this embodiment, it is assume that each of the email items 710 and 720 contain the user-intended information, e.g. email content.

Next, the control unit 160 determines whether to display all of the email items 710 and 720 in the email list by means of the display unit 132. In this case, the email list can be preconfigured so as to show only the unread email items. For this purpose, the control unit 160 identifies the email items containing the representative information or assigned the high priority among all of the email items 710 and 720.

Accordingly, the unread email items 710 can be assigned the priority higher than that assigned to the read email items 720 in the email list. Thus, the control unit 160 configures the unread email items 710 as shown-information items and the read email items 720 as hidden-information items.

Next, the control unit 160 controls such that an unread email list including only the unread email items 710 on the display unit 132.
